Profile bio

About Jonathan Guiang, Phd

Jonathan holds a Ph.D. in Physics from UC San Diego, where he was a Alfred P. Sloan Scholar, and the co-founder and director of the EXPAND program. He received a B.S. in Physics from UC Santa Barbara in 2019 with highest honors and multiple departmental awards. In 2024, he graduated from UC San Diego, having spent 5 years studying proton-proton collision data collected by the CMS detector at the LHC, with a focus on improving our understanding of the universe by making precise measurements of the Higgs boson. He also contributed to innovations at every step of the enormous LHC data pipeline, allowing him to develop a wide range of expertise, from large-scale DevOps to machine learning and artificial intelligence. In addition, he helped coordinate a program he co-founded in 2020 called EXPAND, which provides research opportunities for UCSD undergrads with no prior experience. In his career, Jonathan is interested in leveraging his diverse technical skillset against pressing societal problems like AI safety or combating misinformation. At the same time, he is committed to making a meaningful, positive change in his community, using the leadership and entrepreneurial experience he gained from EXPAND, to contribute to a more equitable future.
